2.6 Connecting the Electrode and Temperature Sensor

To connect the probe to the meter, align the BNC connector slots with
the posts of the meter socket and rotate the connector clockwise until
it locks. Do not force the connector. To remove the probe, rotate the
connector in a counter-clockwise direction until it unlocks, and slide the
connector off the socket.

Insert the mini phono jack of the temperature sensor into the socket on
the meter. Unplug the phono jack when not in use or when measuring pH
without temperature compensation.

2.7 Conditioning the pH Electrode

For best results condition the pH probe before the fi rst use, or if it has
not been used for a long time, by soaking it in pH 4 buffer solution for at
least 1 hour. Rinse before use.
